I love this elegant if “almost useless” machine that Alex Weber created: This little machine uses a so called solar engine to drive the motor. This solar engine is able to collect tiny amounts of energy over time and stores it in large capacitors. When the voltage reaches a certain level, it opens up and […]
We’ve seen papercraft passive amplifiers before, but the Whirlwind from instructables member urant folds away flat so you can stick it into your pocket. [via Life Hacker]
The Molecule Synth offers the elemental components of a traditional keyboard synthesizer — a speaker & amp, a sound generator, and a pitch controller — but presents those elements as pieces that you arrange (and rearrange!) in various combinations to create your own musical device.
This project consists of separate solar circuits that store energy and trigger motors and electronic oscillators in an arrhythmic sequence which is regulated both by the amount of light in the room and by variances in the individual circuits
From Instructables user hydronics comes this electronic bee-counter that mounts over a hive’s entrance, dividing it into many channels, each as wide as a single bee, and each equipped with a pair of IR reflectance sensors. When a bee passes through, the order in which the sensors are tripped reveals if it is coming or going.
“Enough is enough! I have had it with these blankety-blank snakes on this blankety-blank, um…ARM…Cortex-M0, ah, microcontroller.”
Right, so, apologies are now due to hardworking Hack a Day writer Mike Szczys for reducing his latest tasty MCU project to a perfunctory SamJack joke. In point of fact…
This unassuming little board can give your project the power of speech! Parallax’s new Emic 2 Text-to-Speech Module (now available in the Maker Shed) is an easy to use speech synthesis board capable of speaking both English and Spanish. You simply pass it text or numbers over serial and it converts them into a natural […]
